Purrfect Auto Service

I took my pathfinder to these guys to replace front struts and one axle.He gave a reasonable quote and suggested me to change Engine gaskets and Radiators and the total amount came to around 1400$ Iam ok with it as I haven't spent on any major repairs recently for this old car.Once the car was fixed I took it home and the next day to work, all of a sudden CHECK ENGINE light came up . I took the car to these guys during the next weekend and he examined and said the exhaust lines might have been misplaced and asked me to come back during a week day.
So I dropped my car and picked up in the evening he said he fixed it , the next day CHEck engine light came up again.This FARCE continued for several weeks, he keep saying he changed a part or realligned the exhaust hoses some technical jargons.Of cource he did not charge me saying he gauranteed the work but I had to drop the car for 5 times to realize he do not know his stuff.Later I took it to the dealer and they charged me 800$ to fix it saying the hoses are not connected correctly and had to change the canisters.Now I am fighting my case with my Credit Card company to get my money back from these guys....so guys watch out..
